As in the numeral 8, eth or beta glyphs, stem joins can be done with overlapping paths if "Mark for unlink, remove overlap before generating" is enabled in Glyph Info.
This can greatly improve interpolation between glyphs.
The most important glyphs to do this on are:
ampersand, Q, R, e, g, eth, afii10049, afii10097, uni1E9F, q.pcap, r.pcap, ampersand.pcap, q.smcp, r.smcp, ampersand.smcp, Q.alt, R.alt
